There was nothing remarkable in the fact that the corsairs were frequently defeated; what is really strange is that they should have achieved so great a success—­success vouched for by the concrete instance that they established those sinister dynasties on the coast of Northern Africa which were the outcome of their piratical activities.

In speaking of them, historians of later date than that at which they flourished are apt to hold them somewhat cheaply, to dismiss them as mere barbarians of no particular importance in the scheme of mundane affairs; as men who caused a certain amount of trouble to civilisation by their inroads and their plunderings.  That which is certain is that they were for centuries a standing shame and disgrace to the whole of Christendom.

To those who may perhaps be called the pioneers—­that is to say, the men treated of in this book—­a certain amount of sympathy and understanding may be conceded; for they had been driven from the land which had been theirs, it was their countrymen and their co-religionists who were being ground to powder beneath the fanatical cruelty of the Spanish Inquisition.  That which they did was doubtless abominable, but it cannot be contended that they had not received the strongest provocation both from the material and the religious points of view.

Once the “Grand Period” was passed, that period in which such men as the Barbarossas, Dragut, and Ali flourished, the chronicle of the Moslem States founded by them sinks to the degraded level of sheer robbery and murder; of a history of a tyranny established within one hundred miles of the shores of Europe, and of great kings and princes bargaining with piratical ruffians who held in thrall thousands upon thousands of their subjects.  How it came about that the Christian States tolerated such an abuse is one of those mysteries which can never be explained; and if subsequent centuries displayed a greater refinement of manners, a more apt appreciation of all that is softer and kindlier in the human relationships of nation towards nation and of people towards people, they have not perhaps so much to plume themselves upon as had their rude forefathers of the sixteenth century, who, seeing the evil and feeling the effects thereof, did their best to extirpate those by whom this evil was caused.

The question may be asked, how can it be that the lives and actions of such men as these are worth chronicling?  It is because, not only that they modified profoundly the course of history in the age in which they lived, but also because that, hidden deep down, somewhere, in these men stained by a thousand crimes, ruthless, lustful, bloodthirsty, cruel as the grave, was the germ of true greatness, some dim spark of the divine fire of genius.  Contending against principalities and powers, they held their own; in the welter of anarchy in which they lived they proved that there existed no finer fighting men, which alone give them some claim to consideration; but that which is most interesting to watch is the absolute domination obtained by the leaders over their followers.  There is no other record of pirates who commanded on so large a scale; there is none which shows men such as these bargaining on equal terms with the great ones of the earth.
